TECHNICAL FIELD OF THE INVENTION

This invention relates to a method and apparatus for the classificationof hair color and hair color treatment agents for theirinterrelationship, and more particularly to a process and instrument formeasuring color characteristics of hair color and classifiying it anddetermining the effect of a wide variety of hair coloring agentsthereon.

BACKGROUND OF THE INVENTION

Hair coloring agent choices are often made by a consumer based onrelatively vague indications of the color to be expected as a result ofthe use of the agent on an individual person's hair. This approach doesnot take into consideration the color of the hair that is to be treatedand how interaction of that particular individual's hair color with thecoloring agent will affect the resultant color.

No reliable source of information has been available to a privateconsumer regarding what the actual color of her or his hair is and whathair coloring agent will provide the hair color alteration that consumerseeks.

Consequently it can be seen there exists a need for procedures andapparatus that will accurately characterize an individual's hair colorto enable selection of appropriate coloring agents for a desired colorresult. Likewise there exists a need for a reliable process andinstrumentation to permit the use of the accurate color-characterizationof an individual's hair color in the selection of hair coloring agentsto effect hair color alterations of a type desired by the individual.

BRIEF SUMMARY OF THE INVENTION

According to this invention there is provided a method and apparatus foraccurately characterizing the hair color of individuals to enableidentification of the hair color and products suitable to achieve adesired change in hair color, and more particularly a method andapparatus for measuring color factors in an individual's hair color toassign that hair color to a classification previously determined tointeract with identified hair coloring agents to bring about predictablecolor changes.

Through experimentation over a prolonged period, the applicants wereable to compile a vast amount of information relating to coloration ofvirtually every imaginable hair color. Thousands of individual hairsamples were treated with many various coloring agents. The hair colorbefore and after such treatment was accurately, scientifically measuredand characterized using known, reliable color measurement. Hair colorwas then assembled into a large number of categories based on ranges ofthe measured color factors. A database was assembled comprising thedesired changes available through various hair coloring agents and theparticular agents that would effect those changes in human hair to thevarious categories.

Instrumentation was implemented to measure from an individual's hair thecolor factors that operate to place the hair color in one of thenumerous hair color classifications and to identify that classificationto the individual or the individual's hair specialist. In addition, theinstrumentation was arranged to allow for selection of a desiredalteration in hair color, and on the basis of the gathered empiricaldata, hair coloring agents capable of effecting the desired change werelocated from within a database.

In an embodiment of the invention, the process for hair color analysisis carried out by measuring with a measuring instrument the values of anumber of color factors in the color of an individual's hair at varioussites, and then providing an indicator or table having a large number ofhair color classifications defining ranges of those same color factors,and finally comparing the color factors of the indicator or table to themeasured color factors to arrive at a classification of the individual'shair color.

In a preferred embodiment of the invention just described the colorfactors were Hunter L, a and b.

In an instrumentation implementing the process just described, acolorimeter was used to measure the color factors. The indicator ortable having a large number of color classifications was retained incomputer memory, and the comparison was made electronically between thememory-retained classifications and the measured color factors.

To use the process just described a list or menu of possible choices forvarying hair color was presented. Upon selection, that choice, alongwith the hair color classification as previously determined, is usedtogether with a database of hair color classifications and associatedproduct identifications empirically determined to effect the presentedchoices of color changes to locate in that database previously testedhair coloring agents capable of effecting the chosen action.

In one further embodiment of the process described, the color factorsmeasured in an individual's hair color were Hunter L, a and b.Classifications of hair color provided in the indicator or table werepercentages of grey in the hair of the individual. This embodimentenables the coloring of grey hair or partially grey hair to obtain anindividual's natural hair coloring or another preferred hair color. Thisprocedure required the selection of one of a number of categories ofhair colors such as “light brown,” “darkest blond,” “light red,” etc.The indicator or table that identified various hair colorclassifications was divided among broad hair color families or groups ofcategories, and for an individual the particular hair family division ofthe indicator associated with that individual's broad family of haircolor was found. The ranges of color factors in that division were thencompared with the factors measured in the individual's hair to arrive ata classification.

In another embodiment of the invention, to arrive at a hair colortreatment agent, a database of hair color treatment agents andclassifications of color characteristics of individuals was compiled andan individual's color characteristics were determined by measurement ofcolor factors, followed by comparison of those color factors with rangescontained in the database. In one embodiment the color characteristic ofthe individual that provided the basis for comparison was skin color.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Any modern version of two general types of color-measuring instruments,colorimeters and spectrophotometers, is an example of instrumentssuitable for the hair color measurement according to a preferredembodiment of this invention. The basic components of either type ofinstrument are a light source, a sample illumination and viewingarrangement, a means of selecting certain wavelengths of light for themeasurement, a detector of the light reflected from the sample, and somerelatively simple computing capacity. In commercially availableinstruments the main purposes of the computing capacity are to store andapply calibration information and to calculate various color coordinatesfor later use. In FIG. 1, a color measuring instrument 10 isillustrated. An individual person's hair 11 is illuminated by theinstrument as generally indicated by the broken line arrow 12, and theinstrument receives illumination reflected from the hair 11 as generallyindicated by the broken line arrow 13. Based on the illuminationreceived by reflection from the hair, the instrument 10 develops thecoordinates Y, x and y. In FIG. 1 the instrument 10 is a colorimeter,commercially available and suitable for development of the values Y, xand y.

Another type of instrument that can be used in the hair colorcategorization method according to this invention is thespectrophotometer that measures the hair reflectance at discretewavelengths and from these data derives tristimulus values, from whichcan be computed the Hunter color values used to measure hair color forthe purposes discussed below.

Important to the use of a commercial colorimeter of the kind employedfor the color measurement instrument 10 of FIG. 1 is the calibration ofthe instrument using a standard. In the early use of an instrument ofthis kind by the inventors, the “Light Skin” sample from the MacbethColor Checker, described in the publication of C. S. McCamy, H. Marcus,and J. G. Davidson, “A Color-Rendition Chart,” J. Appl. Photogr. Eng. 2,95-99 (1976) was used. A tile of this approximate color was selected forits greater durability as an instrument standard. It was found, however,that the use of the “Light Skin” painted paper as the primary standarddid not adequately avoid the phenomenon known as metamerism, by whichobjects that look alike (have the same perceived color) under some kindsof light sources or to some observers but do not match under other typesof light sources or to other observers. By this phenomenon colorimetersmay not read their colors the same as the average human observer wouldunder the daylight type light source usually employed for visualobservation. This, then could lead to an error in colorimetercalibration.

As an improved primary standard, the skin of a subject whose skin colormeasurements were highly reproducible and in the approximate center ofthe range of skin colors of the human population was selected. Thespectral reflectance factors of the skin of this subject were carefullymeasured on a Macbeth 1500 Plus spectrophotometer (Macbeth, New Windsor,N.Y.); these data are given in column 2 of Table a at the wavelengthslisted in column 1. By using well-established techniques of computercolor matching, carried out on an ACS 1800 system equipped with an ACSSpectroSensor II color measuring instrument (Datacolor International,Lawrenceville, N.J.) a colorant formulation matching this skin color wasdeveloped. The spectral reflectance factors for this match are given incolumn 3 of Table a. It may be seen that the data closely match those ofcolumn 2, indicating the absence of metamerism. Calculations accordingto the CIE 1976 CIELAB system showed that the two data sets match towithin 0.27-0.36 units, less than can be perceived by human colorvision, for daylight, incandescent light, and cool white fluorescentlight, the three most commonly used light sources for the proposedapplications.

The above-mentioned formulation was made up in a stable, durablematerial, and tiles were prepared as instrument standards. The spectralreflectance factors of one of these tiles are given in column 4 of Tablea. It was found, however, that the improvement in calibration resultedin color coordinates that were significantly different from thoseobtained in the many studies made with the earlier system. A decisionwas made to adjust the calibration values of the new tiles in order toachieve consistent results between the new and old methods ofcalibration. Column 5 of Table a gives the adjusted set of spectralreflectance factors for the tile of column 4. The CIE and Hunter colorcoordinates, for measurement with the specular component excluded andcalculated for CIE standard illuminant C and the 1931 2° CIE standardobserver, are also tabulated for each of the samples in the table.

With a suitable standard, basically, calibration is carried out byforcing the colorimeter 10 to give the desired color coordinates Y, xand y mentioned above, while utilizing the colorimeter with the standardtile chosen. The method of calibration is known for particularinstruments and follows a series of steps prescribed by the manufacturerthat need not be detailed here.

In hair color analysis, prior to each test of a subject the subject'shair should be free of dirt. The site should be well dried to avoid anywetness which may interfere with the reflection of light from the hair11 to the instrument 10. In all cases with the instrument correctlycalibrated, the instrument's measuring head or instrument orifice isplaced against the site to be measured. Care is taken to avoid theadmission of ambient light to the instrument. Pressing the instrumenthead firmly against the measurement site prevents the entry of ambientlight. Additionally, it was determined that best results are obtained ifone removes the instrument from the measurement site briefly, betweenilluminations. This can be provided for in software by a conventionaldelaying routine and, if desired, with an appropriate displayinstructing the user to remove the instrument briefly well away from thesubject's hair.

In a colorimeter of the type shown in FIG. 1, at block 10 the instrumenthas an internal microprocessor or other computing capability so that itis able to develop the color coordinates Y, x and y from the measuredvalues X, Y and Z (Y being the same in each case). Certain colorimetersdevelop the Hunter color coordinates L, a and b. Since the degree ofcomputation that the color measuring device 10 (i.e. colormeter orspectrophotometer) internally performs varies, the manner of calculatingthe Hunter values from the tristimulus coordinates is useful to anunderstanding and practice of the invention and will enable correct useof a CPU by appropriate calculation to perform the invention with anycommercially available colormeter or spectrophotometer. Most moderncolor measuring instruments begin with measurement of the tristimulusvalues X, Y and Z. From these can be derived the CIE chromaticitycoordinates x and y:

x=X/(X+Y+Z)  (1)

y=Y/(X+Y+Z)  (2)

The instrument 10 of FIG. 1 outputs the triplet of values x, y and Y asthe starting point for further calculations by a central processing unitwhich can be dedicated microprocessor circuitry or personal computer 15.The remaining two tristimulus values X and Z are available bycomputation as follows:

X=xY/y,  (3)

and

Z=(1−x−y)Y/y  (4)

In the preferred embodiment, in any event, the CPU according to FIG. 1develops the Hunter values L, a and b. The Hunter L,a and b values arethe three values derived by Richard S. Hunter in 1958. Richard S.Hunter, “Photoelectric Color Difference Meter,” J. Opt. Soc. Am. 48,985-995 (1958). The equations for these are:

L=10(Y)^(½)  (5)

a=17.5(1.02X−Y)/Y ^(½)  (6)

b=7.0(Y−0.847Z)/Y ^(½)  (7)

where L is a lightness coordinate whose values correlate better with thevisual perceptions of the lightness of object colors than do values ofY; a is a coordinate denoting redness or greenness, for which positivevalues denote that the color is red rather than its opponent colorgreen, and negative values of a denote the opposite; and b is ayellowness-blueness coordinate, for which positive values denote thatthe color is yellow rather than the opponent color blue, and negativevalues of b denote the opposite. For yellow colors, starting with a=b=0and an appropriate high value of L, which would be a light grey,increasing positive values of b result in a series of colors that may bedescribed as light yellowish grey, pale yellow, light yellow, brilliantyellow and vivid yellow, in turn. Thus b is a measure of the “intensity”of the yellow color.

In the particular arrangement of FIG. 1, wherein the colormeter 10produces the values Y, x and y, the computer 15 derives the Huntervalues L, a and b.

Following the procedure represented in FIG. 2, the colorimeter iscalibrated as described above. The values of Y, x and y are measured foreach of multiple sites on the subject's hair. Preferably the top, eachside, the back of the subject's head, the color of the hair at the rootsand at its ends, are measured. Three measurements are taken at each siteand are averaged to arrive at an Y, x and y for each site and, from theaverage for each site, Hunter L, a and b for each site is calculated.

The values of Hunter L, a and b are compared to the values of Hunter L,a and b of the color categories 1, 2, 3, 4, 5, 6 etc. of the HairCategories table of Appendix A. This, then, identifies the category ofthe subject's hair coloring at each of the measured sites. Each HairCategory in the table of Appendix A has in association with it the haircolor name, such as Black-Cool, Darkest Dark Brown-Cool, etc., anidentification of one or more manufacturer's “Levels” which are commonlyindicated upon a manufacturer's product to indicate products recommendedfor individuals with particular hair color. In other words, theidentification of hair category or classification can also indicate tothe subject or the subject's hair specialist the designation or levelthat the subject should seek out in a particular manufacturer's line ofproducts. The Hair Categories table of Appendix A may further identifyfor the subject or his or her specialist the pigment designation givenby the manufacturers to the particular color.

The hair color categories for the several measured sites, then, can beused by the subject or her or his hair specialist to allow for accurateassessment of the hair color to be dyed and to choose a product for haircoloring. As will be appreciated, the category or classification mayvary from site to site and this will inform the subject or specialistwhether it will be necessary to use varying products or longer orshorter periods of application at varying sites to achieve a haircoloration desired. In other words, dark roots might be treateddifferently than light ends.

In accordance with the further method according to FIG. 3, a haircoloring agent recommendation is made to achieve a subject's desiredcoloration change. Once having determined the correct color categoriesfor each measured site, a menu of possible actions (Appendix B)affecting hair color is displayed and one such action is chosen by thesubject or hair specialist. Using that selection and the hair colorcategory, a database (Appendix C) is consulted as indicated at step 7and at step 8 products are identified from Appendix D of a givenmanufacturer that will accomplish the sought-after result.

The menu of hair color action choices available in step 6 is appended asAppendix B.

The database used in step 7 to arrive at a particular product that willeffect the chosen hair color option for the particular person's haircategory is attached as Appendix C. Certain codes in this appendix thatare used by this database require explanation. The same 75 hair colorcategories 1, 2, 3, 4, etc., and category names as appear in the tableof Appendix A are listed under the heading “Category Name.” Also under“Category Name” the Category Group, A, B, C, D, etc. is designated as inthe Appendix A table. Next, the ranges of Hunter L, a and b defining thecategory appear. Under the heading “CW Level” one of four levels of coolto warm is listed. In these the numeral “1” is coolest, “2” is a bordercolor on the cool side of the cool-warm boundary, “3” is a warm color onthe warm side of the cool-warm boundary, and “4” is a warm color. The“Level” column lists again the product manufacturer's “Level”designations like those listed in Appendix A.

In the Appendix C database, two manufacturers are listed for eachcategory. Opposite each appears a series of numbers such as−1:01−2:01+1:02+2:02. In each of these numbers the first digitrepresents an action which may be chosen from the menu of hair coloroptions. For example in −1:01, the number “−1” making hair colorslightly darker. The number “−2” means “darker,” which is somewhat moredarkening than “slightly darker.” The number “+1” means “slightlylighter” and the number “+2” means “lighter,” e.g. somewhat morelightening than “slightly lighter.” The number after the (:), “01,” is adirection to go to category group A. In category Group A, then, areidentified the manufacturer products of :011. An index, Appendix Dhereto, identifies products of each manufacturer. These are the productsthat will have the desired effect.

From the database of Appendix C it will be seen, then, that, forexample, to darken hair of Categories 2, 3, 4 and 5, “01” appears,making reference to Category Group A1.

The database appended as Appendix B was developed empirically by, first,measuring the Hunter L, a and b of an enormous number of sample hairsfrom the numerous Categories, then applying the colorants of themanufacturers to these hairs and again measuring the Hunter L, a and bto determine the color change effect of the hairs thus colored. This wasdone as well for the lighter ends of these hairs and for darker roots.This was also done for greying hair for use in the grey hair programdescribed below. In this fashion the database of Appendix B was built.

Turning to the block diagram of FIG. 4, characterization of greying haircan be accomplished, following calibration of the instrument at stepone, by selecting one's natural color from the following List Of NaturalHair Color Options.

(Appendix E)

TABLE V LIST OF NATURAL HAIR COLOR OPTIONS 1. If Grey is present inBlack, Dark Brown, Medium Brown or Brown Hair, please press #1. 2. IfGrey is present in Light Brown/Darkest Blonde Hair, please press #2. 3.If Grey is present in Dark Red, Medium Red, or Medium Light Red Hair,please press #3. 4. If Grey is present in Light Red or Red Blonde hair,please press #4. 5. If Grey is present in Medium to medium Dark BlondeHair, please press #5. 6. If Grey is present in Light Blonde Hair,please press #6.

Again, at step three Y, x and y for the natural hair is identified,either by measurement at a natural hair color site on the individual orby the individual's identifying hair swatches considered to be his orher natural color. From Y, x and y, Hunter L, a and b—three measurementsare taken and then averaged to reach average Hunter L, a and b, or inthe case of the swatch this may already have been done so that Hunter L,a and b for the swatch is known.

Further sites containing grey are then measured at step 4 to arrive atY, x and y for these additional sites, which again may be the sides,top, back of the head, roots and ends. The same procedure is followedwith three measurements per site to reach average Y, x and y for eachsite and thereafter calculating average L, a and b for each site. Withthe Hunter L, a and b for natural hair and the Hunter L, a and b for thegreying hair determined, the table entitled “Calculation of Percentageof Grey Hair,” Appendix F, is consulted, which defines the grey haircategories on the basis of percentage of grey.

The percentage grey thus identified is displayed and this represents thecategory for an individual with greying hair. This characterization isused similarly to the previously described characterization or categoryof the table of hair categories attached at Appendix A.

In FIG. 5 the use of the grey hair identification as just described in aprocedure for identifying colorants to achieve a desired result isindicated. After calibration of the instrument as described, the stepspreviously discussed in connection with FIG. 4 are followed to identifythe category of greying hair. Then, at step 7 from the menu of optionsappearing above, a selection of one of the 35 choices is made. Withthat, now the database of Appendix C can be used in exactly the samemanner as described previously. That is to say, the category of hair isfound, the option selected is chosen as −1, −2, +1 or +2. The CategoryGroup designator, 01, 02, 03, etc. is used to identify the appropriatecategory family to go to and in that category family is found theidentifier of manufacturer's hair colorants that will produce thedesired result which is found in Appendix D.

In FIG. 6, a method of using an indicator table to choose hair coloringagents for compatibility with skin coloration entails taking 5measurements for the subjects right cheek and calculating Y, x and y,following calibration of the instrument. Out of range readings arediscarded prior to calculation of Hunter L, a and b based on theremaining three averaged Y, x and y readings. Using the value of Hunterb at step 5, it is determined whether the skin tone type is less than11.5 and consequently cool or equal to or higher than 11.5 and thereforewarm. Using this cool or warm designation the Table attached as AppendixF is consulted to arrive at hair color recommendations.

Appendix F is developed by assessment of Hunter b in the products listedto assess the warmness or coolness of those products and products arerecommended that have the same proportion of yellow to blue as does themeasured skin color.

In FIG. 1 the colorimeter 10 provides Y, x and y to the computer 15. Thecomputer's memory 17 is divided into RAM and ROM.

In the system of FIG. 1, following the routine of FIG. 2, the CPU orcentral processing unit of the computer calculates the Hunter values L,a and b and stores these at selected addresses of the data portion orRAM of memory 17. The data RAM (or nonprogram) portion 18 of the memory17 is indicated in FIG. 1a. A relatively permanent section 18 a of RAM18 stores the data of Table I. A more often revised memory segmentstores the results of the measurements performed with the instrument.Based on a relatively straightforward program retained in the permanentROM memory, from the measurements taken at intervals, the CPU calculatesnew values of L, a and b. The CPU compares these to the L, a and bvalues in Table I and indicates the appropriate hair color category fromTable I, for example on the display 20.

To perform the procedure according to FIG. 3, the RAM memory 18 containsas well the information of the menu of options in Table II, Appendix B.These are called up and displayed at display 20 and, using an inputdevice such as a keyboard 22 or a mouse, a selection is made. Theselection is retained in the more temporary portion 18 b of the RAM 18.

The CPU consults the Table III database of Appendix C, in the morepermanent RAM section 18 a and pulls up the appropriate manufacturer'sproduct identifications in the Table IV, Appendix D for the choice ofmenu items and the hair color category. These are displayed on thedisplay 20.

To accomplish the procedure of FIG. 4 the computer 15's RAM 18 retainsthe Table I information which includes the greying hair categories 61 to68 and the Table VI, Appendix F information giving the manner ofarriving at percentage of grey hair. The CPU inquires of the user viathe display or measurement and is given the natural hair color via theinput. The CPU uses the Hunter L, a and b values and Table I todetermine Color Category or if Table I does not yield a category theTable VI information is employed with L to arrive at a Category usingTable VI. The category is displayed.

To perform the procedures of FIG. 5, the CPU determines thecategory-percentage of grey hair as above, from either Table I or TableVI. The menu of selections, Table II is displayed and a choice isindicated. Using the choice and the category identified the Table IIIdatabase is used to indicate a group or “file” of manufacturer'sproducts in Table IV, which are then displayed on the display 20.

For the choice of hair coloring agent based on skin color the CPUdetermines if Hunter b is above or below 11.5 and based on thisavailable selections from Table VII, Appendix G are chosen anddisplayed.

While particular preferred embodiments of the invention have beendescribed and illustrated, it will be apparent to those skilled in theart that revisions can be made without departure from the spirit andscope of the invention as defined in the appended claims.
